Jute fiber-reinforced composites have become a promising alternative to synthetic fiber composites because of their favorable environmental characteristics, cost efficiency, and good mechanical properties. The present review provides a comprehensive examination of the manufacturing processes and mechanical properties of polymer composites reinforced with jute fibers. This study investigates the influence of several fabrication methods, such as hand lay-up, compression molding, injection molding, pultrusion, etc., on the mechanical properties of the composites. It also provides SWOT analyses of various manufacturing processes of jute fiber-reinforced composites. Important aspects, including fiber orientation, fiber/matrix adhesion, and the effects of different surface treatments on improving mechanical characteristics, such as tensile strength, flexural strength, and impact resistance, are discussed. The difficulties associated with moisture absorption, degradation, and the lack of uniformity in jute fibers, as well as approaches to alleviate these problems, are presented. The goal of this study is to establish a basis for future investigation and advancement in enhancing the mechanical properties of jute fiber-reinforced composites.

In this paper, expanded perlite based particulate composites for the application in building insulation board are studied for compressive behaviour. Composites with a density range from 0.452 to 0.640 g/cm3 are manufactured using floatation method by varying binder content (sodium silicate solution and corn starch as binder) and the degree of compaction. Compressive strength and modulus are investigated based on two manufacturing parameters (i.e. Compaction ratio and Water/SSS ratio) and the density of the composites. Compressive strength and modulus were found to be linearly dependent on the density however the trend for compressive strength and modulus were found to be different. The change of compressive modulus with respect to increasing density is found to be different for different compaction ratio which is not significant in the case of compressive strength. The range of specific compressive strength of the composites from 4.27 to 5.08 MPa/(g/cm3) was found to be suitable for the building insulation board application when compared with existing literature.
